What Causes Angel Wing Leaves to Turn Brown & Dry?

Plant caladiums in a sheltered, shaded location.

Angel wings (Caladium bicolor) is either grown as an annual plant or a houseplant in most parts of the U.S., but is can be grown outdoors year-round in U.S. Department of Agriculture plant hardiness zones 9 and 10. Whether you're growing it as a houseplant or an outdoor plant, brown, dry leaves usually mean too much sunlight or not enough water.

Growing Conditions

Angel wings are fairly diseasenresistant, and browned leaves are most likely caused by improper growing conditions. Angel wings grow best in partial or bright shade. In full sun, the leaves may scorch, especially in hot climates. Angel wings need consistently moist, rich soil. Drought conditions can also cause brown leaves. If the plants are placed beneath a tree, use a drip system to ensure they get enough water. Another cause of brown leaves might be foliar fertilizing sprays. Apply a diluted 10-10-10 liquid fertilizer twice a month directly to the soil, rather than the leaves. Combine 1 tablespoon liquid fertilizer with 1 gallon of water, or according to package directions.

Disease

Anthracnose may occasionally cause brown leaf spots, but is rarely serious. Remove and discard the dead leaves. Mites and aphids can cause wilted or browning leaves. Dispatch them by spraying the plants with a steady stream of water.
